The HRC-compatible gripping modules from Weiss Robotics have been specially developed for the interaction of humans and robots. They already meet the DGUV recommendations for collaborative robot systems as well as the requirements of ISO/TS 15066 standard and thus considerably simplify the risk assessment of the entire plant.
SAFE GRIPPING FORCE CONTROL
Instead of just limiting the motor current, as is customary in the industry for adjusting the gripping force, Weiss Robotics' collaborative grippers feature a model-based sensor-less gripping force control, which controls the gripping force very precisely and independently of external influences. Thus, the handling of otherwise difficult-to-grip workpieces such as brittle or yielding parts is process-reliable.
The glare-free illuminated ring integrated in the gripping module intuitively communicates the system’s current state of the system based on various light patterns and colors. This facilitates the assessment of the plant, whereby the collaboration between humans and robots can be carried out particularly smoothly and safely.
GRIPPING FORCE RETENTION – PERMAGRIP
The innovative gripping force retention developed by Weiss robotics preserves the gripping force on the workpiece, even if the power supply to the gripper is interrupted unexpectedly. Thanks to the integrated absolute sensors the production can continue even without referencing when the power supply is restored. PERMAGRIP is the first HRC-compatible gripping force retention system that does not snap shut in the event of manual workpiece removal, making it safe to use in direct interaction with humans.
